I didn't know him personally, but Todd Johnson's (aka CanadianCougar) sister is a close friend to our family. Last night Todd and his son, Levi, were tragically struck and killed by a vehicle in Utah. He was a huge BYU fan, but hadn't been on Cougarboard much since going blind:

I know we don't normally link to facebook profiles, but if it helps to get to know these heartbreaking circumstances, Todd's page is here:
